i put the aftermarket xenon upgrade in the fog lights, but the computer don´t recognize the xenon system, and the signal appears (don´t have fog lights !), then when i turn on the switch of the fog lights some times the fog lights turn on, and some times not, how can i fix this problem, any idea?

 

The new bulbs may have different resistance , confusing the computer. Are you using ballasts with the fog lights? In the past fog lights were usually amber not blue ,6K.

 

yes i am using ballast, maibe can it be the fuse

 

It's not the fuse. If afuse blows it will never work.

 

you need 15 or 30amp fuses (don't remember right now, i will in the morn...) in order for HID's to work....

 

15. but crazyhawk is right. if it was the fuse, they wouldn't come on at all

 

i don´t think that the fuse make it turn on or off the lights some times, i just think that the amp of the fuse maibe confuse the ecu and that is why the computer sometimes it send the message (fog lights failure)

 

it sounds to me like a faulty connection. could be anywhere.

 

Either fuse has near zero resistance. As I said before , the resistance of the ballast , xenon combination might be different from the origonal bulbs.

 

did you have any idea to fix this problem ? can some body help me? a frend put the same upgrade in his b5, look the pics:
